22 - add the opacity fill type - an adaptor that modifies the opacity of
23 another fill.

TC
25Bug fixes:
26
27 - the conv filter now enforces that the sum of the coefficients is
28 non-zero. Also, rather than skipping pixels off the edge off the
29 edge of the image, the closest edge pixel is used. Previously
30 dividing by the zero sum of coefficients could cause invalid
31 results or runtime exceptions.
32 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
33 this bug.

38Bug fixes:
39
40 - release image row and comments memory on all error returns in gif
41 reader
42
43 - handle zero length extensions, previously this would cause a null
44 pointer dereference
45 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

TC
47 - an integer division meant that preview scaling to below 1 pixel
48 wide or high (which isn't too useful anyway) was calculating using
49 NaNs on most platforms, and causing an exception on others.
50 Thanks to David Cantrell for producing a backtrace of the crash on
51 his Alpha-NetBSD CPAN test box which made it possible to track this
52 down.

91
92 - correct documentation of default of raw image interleave read
93 parameter
94 https://rt.cpan.org/Ticket/Display.html?id=42074
95
96 - add raw_ prefix to raw read parameters, though the original names
97 still work.
98
99 - fail the read if an invalid raw_interleave parameter is supplied
100
101 - warn if no interleave or raw_interleave parameter is supplied,
102 since the documented default was wrong, and incompatible with the
103 write format
104
105 - for reading raw images, if raw_storechannels > raw_datachannels,
106 set the extra channels in the image to 0
107
cd476e58
TC
108 - when probing for executables like freetype-config, search for .bat
109 and .cmd on MSWin32, as well as .exe.

TC
140 - an optimization skipping 0 src alpha values could cause the
141 rubthrough() to read past the end of a buffer.

143
5c0d0ddf
TC
144 - corrected a reference leak where writing GIFs would leak memory.
145 This could also happen calling to_paletted().
146 Also documented the underlying long existing feature where the
147 colors parameter is filled with the generated color table and added
148 tests for it.

153
c586eb58
TC
154 - add limited tests for Imager::ExtUtils
155
156 - make Imager::ExtUtils->includes use an absolute path, since
157 a relative path could cause failures using Inline::C.
158 http://rt.cpan.org/Ticket/Display.html?id=37353
159
6b22ba84
TC
160 - re-arrange the POD for Imager::Font::BBox:
161 - mark total_width(), pos_width(), end_offset() obsolete, since
162 they're mostly for backwards compatibility
163 - group width methods and height methods

TC
167===========
168
169Bug fixes:
170
171 - In some cases when an error occurs reading those parts of a JPEG
172 file after the image the scan-line buffer could be freed a second
173 time. In cases where the the error occured while reading the image
174 data it's possible that the buffer could have leaked.
175 Thanks to Gabriel Vasseur for reporting this and help in tracking
176 it down.
177

TC
178 - the gif_screen_height tag was overriding the screen width and being
179 ignored for the screen height when present.

TC
185This is a bug fix release. This includes a fix for a possible
186security issue.
187

TC
188Bug fixes:
189
e02d22d2
TC
190 - Possible security issue: The floating point sample path for image
191 based fills had a buffer overflow. This would overwrite the end of
192 a malloc()ed buffer with double precision floats.
193 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 194 CVE-2008-1928
e02d22d2 195
de470892
TC
196 - check that the result of fileno($fh) is defined rather than simply
197 true when read() or write() is supplied with an fh parameter.
198 http://rt.cpan.org/Ticket/Display.html?id=35139
199
200 - i_scale_axis() wasn't checking the result of i_img_new_ch()
201 resulting in a SIGSEGV when attempting to scale an image to a size
202 too large to fit in memory. This is a NULL pointer access issue,
203 not a buffer overflow.
204 Added a check for the failure.
205 scale_calculate() (and hence scale()) will now fail if any of the
206 scale size parameters are a reference.
207 http://rt.cpan.org/Ticket/Display.html?id=35172
208
04f85f63
TC
209 - Regression: filling a greyscale image with a hatch used the wrong
210 color channels from the supplied fg/bg colors.
211 https://rt.cpan.org/Ticket/Display.html?id=35278
212
a256aec5
TC
213 - fixed a related problem for image fills.

33b0ffa6
TC
216===========
217
242d7497
TC
218This release primarily contains changes to improve ease of use -
219rather than you having to convert images to the appropriate number of
220channels, Imager handles it internally. How to handle drawing colors
221and the default combine mode is a thornier problem left for some other
222release.
223
d1555273
TC
224 - the font libraries are now only initialized when needed.
225 http://rt.cpan.org/Ticket/Display.html?id=28825
226
9b1ec2b8
TC
227 - moved the imtoc.perl code into Imager::Preprocess
228
229 - paste() and rubthrough() now adapt the source image data to the
230 destination, so you can now safely paste/rubthrough from greyscale
231 images to color images or back, or from alpha channel images to
232 noalpha channels or back.
233 https://rt.cpan.org/Ticket/Display.html?id=30908
234
235 - rubthrough() now falls back to pasting when the source doesn't have
236 an alpha channel. This effectively treats the source as having a
237 max alpha channel, the right thing to do.
238 http://rt.cpan.org/Ticket/Display.html?id=29944
239
240 - re-worked most of the area filling code to use a common set of
241 functions when filling.
242 Corrected normal combine mode.
243 Rewrote most of the combine modes to match the way the SVG draft
244 defines them with respect to a translucent source and destination.
245 Added tests for translucent source and destination.
246 Added tests to check 8-bit/sample and double/sample combines work
247 similarly.

TC
250 - writing a 2 or 4 channel image to a JPEG file will now write that
251 image as if composited against a background, black by default,
252 overridable with the i_background tag/parameter.

TC
265Bug fixes:
266
267 - Imager::Matrix2d->translate() now only requires one of the x or y
268 parameters.
269 http://rt.cpan.org/Ticket/Display.html?id=29937
270
2757bad0
TC
271 - mixing qtype scaling now sets all channels of a pixel to zero if
272 the pixel has zero coverage (zero alpha). This should produce more
273 compressible output files.
274 http://rt.cpan.org/Ticket/Display.html?id=32324
275
3da08517
TC
276 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
277 Noticed when I saw:
278 https://bugzilla.redhat.com/show_bug.cgi?id=166254
279 I'm not changing the #! lines of the sample code, since it's sample
280 code, not intended for installation.
281 http://rt.cpan.org/Ticket/Display.html?id=33408
282
242d7497
TC
283 - some TGA images weren't being detected correctly as TGA images
284 https://rt.cpan.org/Ticket/Display.html?id=32925
285
286 - handling of the left-over bit for 16-bit/pixel TGA images has been
287 changed to match the behaviour of the GIMP. Previously the bit
288 being set was treated as an opaque pixel, but one user reported a
289 problem with loading such an image. I haven't been able to find any
290 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
291 I'll match it's behaviour. See issue 114913 in the GIMP's
292 bugzilla.

298 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
299 to /path under your home directory.

TC
302 - the old dynaload code used Mach API functions to load dynamic
303 libraries on Mac OS X. These APIs have been deprecated in OS X
304 10.5 and were causing some build problems.
305 So henceforth Imager uses the dlopen() family of functions, and you
306 will need version 10.3 or later of OS X.
307

TC
334 - major TIFF support re-work
335 http://rt.cpan.org/Ticket/Display.html?id=20329
336
337 - added a C level image interface for accessing samples from 1-32
338 bits, exposed this at the perl level in getsamples()
339
340 - the conv filter now works at floating point precision for high bit
341 images
342
343 - added is_bilevel method to test whether an image should be written as
344 a bilevel image if the image format supports it.
345
346 - added -log-stderr as an Imager import list option
347
348 - added some important types to Imager::APIRef

TC
449 - the mask for ICO/CUR images is now applied as an alpha channel to
450 the returned image. For the old behaviour, supply ico_masked => 0

452 using Imager as a general image processor.

455Bug fixes:
456
457 - in some cases it's possible for giflib/libungif to return color
458 indexes outside the range of colors defined by the image's palette.
459 We now expand the palette to match the indexes used.
460 Thanks to Gabriel Vasseur for reporting this.

465 - to avoid confusion, channels not present in the image are returned as
466 zero by getscanline(). This has no effect on the C level i_glin()

468 channels.

610Imager 0.55 - 16 Dec 2006
611===========
612
613This is primarily a bug fix release.
614
615Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
616
617There is one new feature:
618
619 - the Win32 font driver now supports UTF8 (RT 22166)
620 http://www.cpanforum.com/threads/3276
621 http://rt.cpan.org/Ticket/Display.html?id=22166
622
623Several bugs were fixed:
624
625 - the string() method would not output the string "0"
626 http://rt.cpan.org/Public/Bug/Display.html?id=21770
627
628 - fills.c was failing to compile on Solaris 10 (compiler unknown)
629 http://rt.cpan.org/Public/Bug/Display.html?id=21944
630
631 - the gif_disposal and gif_user_input tags weren't being read from
632 the file correctly
633 http://rt.cpan.org/Public/Bug/Display.html?id=22192
634
635 - gif.c was failing to build under MSVC
636 http://rt.cpan.org/Ticket/Display.html?id=23922
637
638 - in some cases strings passed to the string() method were treated as
639 terminated by NUL (chr 0)
640 http://rt.cpan.org/Public/Bug/Display.html?id=21770
641
642 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
643 that's the default build name for zlib on Win32.
644 http://rt.cpan.org/Ticket/Display.html?id=23064
645
646 - search $Config{incpath} for headers too, which we should have been
647 doing all along.
648
649Win32 font driver fixes:
650
651 - the global descent value from bounding box was the wrong sign
652 http://www.cpanforum.com/threads/3276
653
654 - if the first or last glyph overflowed the left or right side of the
655 advance width they would be clipped
656
657
658Imager 0.54 - 14 Sep 2006
659===========
660
661This is primarily a feature release:
662
663 - a new qtype value 'mixing' has been added to the scale()
664 method. This is faster than 'normal', slower than 'preview'. This
665 is based on the method used by pnmscale, and seems to produce less
666 blurry results than normal.
667 http://rt.cpan.org/Public/Bug/Display.html?id=20677
668
669 - the rubthrough() method can now render onto images with an alpha
670 channel.
671 http://rt.cpan.org/Ticket/Display.html?id=20678
672
673 - the read_multi() method now falls back to calling doing a single
674 image read via the read() method and write_multi() will now fall
675 back to calling write() if a single image is supplied. This means
676 you can simply call the read_multi() or write_multi() functions
677 without having to check if the type is formatted by that method.
678 http://rt.cpan.org/Ticket/Display.html?id=19457
679 http://rt.cpan.org/Ticket/Display.html?id=19458
680
681 - the GIF loop extension can now be written. If you don't have
682 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
683 should upgrade.
684 http://rt.cpan.org/Ticket/Display.html?id=21185
685
686 - getscanline() and setscanline() can now read/write palette index
687 based data from/to the image for paletted images, by setting type to
688 'index'.
689 http://rt.cpan.org/Ticket/Display.html?id=20338
690
691 - we no longer hassle you to disable GIF support
692 http://rt.cpan.org/Ticket/Display.html?id=20687
693
694 - minor documentation fixes
695
696
697Imager 0.53 - 26 Jul 2006
698===========
699
700This is a bugfix release.
701
702Some test code was left in a code path not covered by the test
703suite. A test was added to cover this code path and the test code was
704removed.
705http://rt.cpan.org/Public/Bug/Display.html?id=20705
706
707
708Imager 0.52 - 25 Jul 2006
709===========
710
711This is primarily a feature release, but contains a fair few bug
712fixes, new features:
713
714 - ability to read and write MS Windows ICO and CUR files
715
716 - you can now add file format plugins to support new file formats
717
718 - add POD coverage tests
719
720 - setcolors() and addcolors() now accept color names and so on
721 instead of requiring Imager::Color objects.
722 http://rt.cpan.org/Ticket/Display.html?id=20056
723
724 - flood_fill() can now fill to a specified border color instead of
725 just to the area the same color as the seed.
726 http://rt.cpan.org/Ticket/Display.html?id=19618
727
728
729Bug fixes:
730
731 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
732 calculating the advance width.
733 http://rt.cpan.org/Public/Bug/Display.html?id=20554
734
735 - bounding_box for the T1 driver wasn't including leading and
736 trailing spaces in the bounding box as the other drivers did, it also
737 produced strange results for empty strings or strings containing only
738 spaces
739
740 - when reading CMYK jpeg images they were being transferred to the
741 image object as is, producing a four channel image. It only looked ok
742 due to an old still unfixed Photoshop bug. We now convert from the
743 inverted CMYK that photoshop (and Corel for example) produce into RGB.
744 http://rt.cpan.org/Ticket/Display.html?id=20416
745
746 - reading a CYMK TIFF would result in a 4 channel image, reading any
747 image with more than 4 channels (eg. RGB with 2 alpha channels) would
748 result in an error.
749 http://rt.cpan.org/Ticket/Display.html?id=20415
750
751 - added /usr/local/include to the default include search path, since
752 we were already searching /usr/local/lib for libraries.
753
754And various minor fixes and documentation updates.
755
756
757Imager 0.51 - 23 Apr 2006

777 or 4 channel image to jpeg or a 2 channel image to tga where the
778 output is an in-memeory buffer.
779 http://rt.cpan.org/Public/Bug/Display.html?id=18397
780
